The Experience

Heat, cool, rest, repeat.

Start with heat. Step out into cool salt air. Rinse under the outdoor shower. Come back warmer, slower, lighter.

Two guests in the cedar sauna — one ladles water onto the stove while the other leans back on the lower bench

01 / Heat

Step into the sauna and let it build.

Cedar walls. Quiet light. The slow climb of temperature against your skin. Stay until the heat asks something of you.

02 / Cool

A reset under cool salt air.

Out onto the deck. Under the outdoor shower. A few breaths that feel impossibly long, and the heat releases — sharper, clearer, awake.

03 / Rest

Slow down. Breathe deeper. Stay longer.

Wrap in a towel. Watch the light move across the bay. Then back in for another round. Heat, cool, rest, repeat.

About

A small boat on a quiet bay.

“Built for small groups. Designed to disconnect you for a while.”

Coho Saunas is a Bellingham-born cedar sauna, built in town for the people who live by this bay. The vision was simple — a boat that connects people to the water, and the water to its people. Close to the bay, away from everything else.

Word is getting around.

Info

Everything you need to know.

Quick answers before your session. If we missed something, write us at cohosaunas@icloud.com.

  • There is now — and it floats. Coho Saunas is a cedar-lined floating sauna on Bellingham Bay, docked at Hotel Bellwether on Bellingham's downtown waterfront. About ninety minutes north of Seattle and an hour south of Vancouver, BC. Book a communal spot or take the whole boat private.

  • Swimsuit, sandals, a robe if you want one. We've got towels and water onboard.

    No glass on the boat, please. There are no lockers on the dock yet — leave valuables in your car or at the hotel front desk. Down the road we'll carry our own robes and hats; not yet.

  • A propane-heated, cedar-lined floating sauna anchored on Bellingham Bay. Six guests maximum. Heated to 175–190°F.

    Western red cedar walls. We chose propane over wood for cleaner combustion, quieter sessions, and consistent heat between bookings. Splash water on the rocks for steam.

  • Two ways to enjoy Coho Saunas: 75-minute dockside sessions at Hotel Bellwether or 2.5-hour cruises on Bellingham Bay.

    Both offer private and communal options for up to six guests. Enjoy the heat, cool off on deck or in the water, and take in the views.

    Docked sessions run daily from 8:00 AM into the evening. Please arrive 10 minutes before your session.

  • Between heat cycles you'll step out onto the deck — cool salt air, the outdoor rain shower, the bay breeze. That contrast is what resets you.

  • Docked sessions (75 min) — Communal $55 per person · Private $255 for the boat. Wednesday Wind Down: communal docked sessions are $45.

    Bay cruises (2.5 hours) — Communal $120 per person · Private $750 for the boat.

    Looking for a custom charter, partner event, or sunrise trip? Write us at cohosaunas@icloud.com.

    Hotel Bellwether guests book docked sessions through the front desk.

  • Gift cards are redeemable for any session — docked or out on the bay, communal or private. Buy a gift card.

  • We sail rain or shine — this is the Pacific Northwest. Sessions only cancel for lightning, sustained high wind, or unsafe water conditions. If we cancel, you'll get a full refund or reschedule.

  • Every bay trip is run by a US Coast Guard–licensed captain. The boat carries all required safety equipment — life jackets, communications, and throwables — and we follow strict weather thresholds before departure.

  • Full refund up to 36 hours before your booking — every session type, docked or out on the bay, communal or private.

    Anything inside 36 hours is non-refundable.

  • The boat is reached by a dock ramp; the sauna entry has one step. Write us before booking if you have specific needs and we'll figure it out.

  • Swimsuits in the sauna. No alcohol during sessions. No soap or product in the outdoor shower — the water rinses straight back to the bay.

    Eighteen and up on shared sessions. Younger guests are welcome on private bookings (the whole boat is yours).

    Voices low: someone next to you came here to disconnect.

  • No bathroom on the boat. Use the Hotel Bellwether lobby restroom before your session — the dock is a one-minute walk from the front door.

  • Bellingham Bay — the dock is at Hotel Bellwether on Bellingham's waterfront. Free guest parking at the hotel; street parking nearby.
